SwingUtilities

public final class SwingUtilities
extends Object

A collection of utility methods for Swing. All show* methods delegate their work to the corresponding method in JOptionPane, with two differences:

• SwingUtilities's method may be invoked from any thread. If they are invoked from a non-Swing thread, execution will be delegate to the Swing thread and the calling thread will block until completion.
• If a parent component is a JDesktopPane, dialogs will be rendered as internal frames instead of frames.

2.0

Method Detail

toFrame

public static Component toFrame(Component owner,
                                JComponent panel,
                                String title,
                                WindowListener listener)

Insert a Swing component into a frame. The kind of frame depends on the owner:

• If owner or one of its parent is a JDesktopPane, then panel is added into a JInternalFrame.
• If owner or one of its parent is a Frame or a Dialog, then panel is added into a JDialog.
• Otherwise, panel is added into a JFrame.

Parameters:

owner - The frame's owner, or null if none.

panel - The panel to insert into a frame.

title - The frame's title.

listener - A listener to receives frame events. If non-null, then this listener will be registered to whatever kind of frame this method will constructs. In the special case where this method constructs an internal frame and the listener is not an instance of InternalFrameListener, then this method will wrap the listener into an InternalFrameListener.

Returns:

The frame. This frame is not initially visible. The method Component.setVisible(true) must be invoked in order to show the frame.
